JANUARY 2020 I DESIGN007 MAGAZINE 77 The technical support teams of reputable sup- pliers have a wealth of experience to call upon, and should it become necessary, they have the expertise to modify chemical formulations to meet your particular application needs. I hope the points covered this month have been informative, and please look out for my next column, where I'll cover more issues on getting the most out of encapsulation resins for seamless circuit protection. In the meantime, please contact us if you have any questions you would like to ask. DESIGN007 Alistair Little is global business/ technical director—resins—at Electrolube.

Pay particular attention to the corners. Continue mixing vigorously for another couple of minutes. On a flat surface, use the clip to push the mixed material into the half of the pack with the angled seal. Roll up the other end of the pack to the bottom edge of the mixed resin. Cut the corner of the pack off and slowly de- cant the resin over the PCB or into the enclo- sure. Allow the resin to flow so that any air under or between components or wiring can be displaced. For complicated geometries, it might be better to add the required amount of resin in multiple stages to allow the air to be released, control the exotherm experienced by the components, and to obtain the desired thickness. If adding a second layer of resin, wait until the first layer has gelled before add- ing the second. If in any doubt, it is always advisable to dis- cuss with suppliers which type of resin sys- tem is most appropriate for your application. The White House proposed regulatory principles to govern the development and use of artificial intelli- gence (AI) aimed at limiting authorities' "overreach" and said it wants European officials to likewise avoid aggressive approaches. In a fact sheet, the White House said federal agencies should "conduct risk assessment and cost-benefit anal- yses prior to any regulatory action on AI, with a focus on establishing flexible frameworks rather than one-size- fits-all regulation." The Trump administration said agencies should "pro- mote trustworthy AI" and "must consider fairness, non- discrimination, openness, transparency, safety, and se- curity." As an example, the White House cited the Food and Drug Administration, which is currently considering how to regulate the use of AI and machine learning tech- nologies by medical device manufacturers. Some U.S. states have raised concerns about AI appli- cations. California's legislature in September passed a three-year ban on state and local law enforcement using body cameras with facial-recognition software, the latest curb on technology that some say poses a threat to civ- il liberties. Some U.S. cities have also voted to bar facial- recognition technology by law enforcement. A 2018 study from consultancy PwC said 30% of jobs around the world are at risk of automation by the mid- 2030s, including 44% of workers with low education. The study also found automation could boost global gross do- mestic product by $15 trillion by 2030. The White House held a meeting on AI in 2018 with over 30 major companies from a variety of industries, includ- ing Ford Motor Co., Boeing, Amazon, and Microsoft, vowing not to stand in the way of the technology's development.
